Hi Manuel, We've been placing QFN's with our CP6's for a long time now. We use vision type 10 just like you describe. I wouldn't bother with front lighting & trying to pick up the leads. Inspecting the leads doesn't provide better accuracy. I would

If you want to buy a Juki machine or any machine for that matter, then be ready with money in hand and you set the price you are willing to buy at today. In my experience alot of Asian Brokers want your best price up front, and then tell you it's too

I have always been under the impression that you want the flux make-up of your cored wire and supplemental flux (squeeze bottle) to be as identical/compatible as possible. I was just looking over a manufacturers datasheet for a resin-based cored wir

This table, is it in a database? And is it indicating the number of component, solder insp. etc based on one board or one panel? It needs to be based on the total number of inspection on your panelized pcb. The equation works, you may just be look

Hello, i don't know if is possible to dispense paste but for reduction of cost we use a diferent type of stencils, from aluminium of 0,2 mm, purchased from a typography of newspapers. Ofcourse the pcb for what we use this stencil are simple. But th

I heard that one can create the stacked/staggered microvias in the layers 1-2 & 2-3 and skip microvia in the layer 1-3 of 6 layer stack up, when the prepreg is between layers 1 & 2 and the other prepreg is between the layers 2 & 3. I want to know w

As with most Aois centroid data is very time saving when your pcb has 20 or more components. This of course can be variable with the quality of the data and your ability to modify it to suit your needs. Omron systems can scan your pcb and merge the

Possible route causes of bridging on fine pitch ICs are; too much paste (stencil aperture wrong), poor print quality (paste smudges during printing), pcb pads not flat depending on the solderable coating, paste has poor cold slump properties, too muc

Has anyone had any experience with SANSDA? We have a board loader that was bought used with no documentation. We have tried to contact them requesting schematics or a SMEMA manual to no avail. The loader is not completing the circuit telling the d

The PPS helps to prepare a program off-line without affecting on-line production. However, there are certain efforts that we must consider, such as identifying the part orientation on feeder vis-a-vis its placement orienation on PCB, and confirming s
